MULTIPLE HEATING GAS-BURNER.

SPECIFICATION formingpart of Letters Patent No. 41 1,648, dated September 24, 1889.

Application filed June 6, 1887. Serial No. 240,422. (No model.)

.To all whom it may concern.-

Be it known that I, ALBERT J. Dorv, of' Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Multiple Heating Gas- Burner, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a plan view of one form of my IO improved multiple burner. Fig. 2 is a side elevation, partly in section, taken on line in Fig. 1. Fig. 3 is a horizontal section taken on line 3 y in Fig. 2 of the central part of the burner. Fig. Iis a partial plan view of a ring-burner constructed according to my improvement, and Fig. 5 is apartial plan view of a multiple ring-burner constructed according to my improvement.

Similar letters of reference indicate corresponding parts in all the views.

There a large flame-surface is desired, it is impracticable to secure it by means of alarge perforated ring or a seriesof perforated rings receiving the combustible mixture in 2 5 one side of the rings, as the friction of the gas in its passage from the point of supply to the part of the ring remote from the said point causes an injurious diminution of the gas-pressure at the remote point.

The object of my invention is to provide a gas-burner in which the gas will be evenly distributed to all parts thereof, so as to secure uniform heating and a uniform combustion of the gas.

My invention consists in a series of radial arms having gas-burning orifices at their extremities, and provided at their intersection with a gas-supply nozzle having as many gasorifices as there are arms, and a central air- 40 supply common to all the arms.

In the simplest form of my improved burner the hollow arms A radiate from a common center B and are provided at their extremities with upwardly-turned nozzles C, from 5 which the combustible mixture issues. At the intersection of the said arms is supported the gas-nozzle I), having orifices a corresponding in number and position with the hollow arms A. In the present case the arms are formed integrally in one casting, and are approximately semicircular in cross-section, and the open side of the said arms is closed bya cross-shaped plate E, having a central aperture e larger than the gas-nozzle I). The plate E is held in place by bolts f, and the gas-nozzle D is connected with the gas-supply pipe F.

Then it is desired to employ an annular burner, the ring G is formedupon the ends of the arms A, and provided with holes 9 for the escape of the combustible mixture.

In Fig. 5 is shown a burner in which each arm A is provided with a small perforated ring G. In these cases the arrangement of the gas-nozzle and air-opening is the same as as that shown in Figs. 1, 2, and 8.

By means of my improvement the gas is projected directly to the point of use without undue loss by friction, and as a consequence every part of the flame of the burner is uniform.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A multiple gas-burner consisting of a central chamber 13, having a series of hollow arms A radiating therefrom, provided at their ends with gas-jets, a gas-nozzle D, secured within said central chamberh, provided with separate gas jets or orifices a, delivering gas into each of said radial arms, said chamber B being perforated at its base with an annu lar or central aperture 0, surrounding the gasnozzle I), said parts being constructed, combined, and arranged substantially as set forth.

2. In a multiple gas-burner, the combination of the following parts, viz: a series of hollow arms A, cast in approximately semicircular form and integrally with thecentral chamber I3, a base-plate for both of the same, consisting of the cross-shaped plate E, having an annular central air-aperture e, a central gas-nozzle D, provided with gas-orifices (L and secured within said chamber B, and pro jecting downward through the center of the aperture 6 and communicating with the gassupply pipe F, said parts being constructed, combined, and arranged substantially as set forth.

ALBERT J. DOTY.
